[osg-users] Why ref_ptr node can not release memory immediatelly?

[John Lee]

Hi,

In my appllication, there are many child nodes in my root node. When i dynamically remove its child node, i find the memory will not free immediatelly, it will free sometimes, maybe it will free when i keep removing a few child nodes, or it will free when i remove all child nodes? Why this happens? And can anyone tell me how to free the scene memory immediatelly? 

Thank you!

Cheers,
John
